Replace text in csv without uppercase and spaces - batch-file

Question

this script replaces a bit of text within a scv with the filename of the csv.
#echo off
setlocal enableextensions enabledelayedexpansion
for /R %%i in (*.csv) do (
ren "%%~i" temp.tmp
(for /F "usebackq tokens=*" %%f in ("%%~dpitemp.tmp") do (
set "line=%%f"
set "line=!line:REPLACE=%%~ni!"
echo(!line!
)) > "%%~i"
del "%%~dpitemp.tmp"
)
endlocal
So say the file was called CSV File. The text would be replaced with "CSV File". My question is how do i format that text with no spaces or uppercase letters?
So my files called "CSV File", but the replacement is "csv-file". I've tried to strip out the spaces first so I've tried this:
#echo off
setlocal enableextensions enabledelayedexpansion
for /R %%i in (*.csv) do (
ren "%%~i" temp.tmp
(for /F "usebackq tokens=*" %%f in ("%%~dpitemp.tmp") do (
::Tried to strip out the spaces from %%~ni
set %%~ni=%%%~ni: =%
set "line=%%f"
set "line=!line:REPLACE=%%~ni!"
echo(!line!
)) > "%%~i"
del "%%~dpitemp.tmp"
)
endlocal
Doesn't work with that, anyone know why? I did get this working:
set "line=!line: =-!"
But I can't do that as it'll effect the whole csv. So I'm not sure if there's a way to tell that line to just effect the replacment text?
Edited code:
#echo off
setlocal enableextensions enabledelayedexpansion
for /R %%i in (*.csv) do (
ren "%%~i" temp.tmp
(for /F "usebackq tokens=*" %%f in ("%%~dpitemp.tmp") do (
set "line=%%f"
echo %%~ni
set MyVar=%%~ni
set MyVar=!MyVar: =-!
set MyVar=!MyVar:,=!
echo !MyVar!
set "line=!line:REPLACE=!MyVar!!"
echo(!line!
)) > "%%~i"
del "%%~dpitemp.tmp"
)
I've managed to strip out the spaces and a comma, so just working on how to get that !MyVar! in my replacement.

Answer 1

I'd use powershell as a tool for this.
From cmdline:
> type "TEST FILE.CSV"
One,two,three
bla,REPLACE,blubb
REPLACE,test,blah
tralala,blah,REPLACE
> for /f "delims=" %A in ('Dir /B/S "test*.csv"') do #powershell -Nop -c "(Get-Content '%~fA') -Replace 'REPLACE',('%~nxA').Replace(' ','-').ToLower()|Set-Content '%~fA'"
> type "TEST FILE.CSV"
One,two,three
bla,test-file.csv,blubb
test-file.csv,test,blah
tralala,blah,test-file.csv
In a batch file double the %-signs
#Echo off
for /f "delims=" %%A in (
'Dir /B/S "test*.csv"'
) do powershell -Nop -c "(Get-Content '%%~fA') -Replace 'REPLACE',('%%~nxA').Replace(' ','-').ToLower()|Set-Content '%%~fA'"
